2 and for Bjorken
x between 3 · 10
−5 and 0.32 using data ...collected by the HERA experiment H1 in 1994. The data represent an increase in statistics by a factor of ten with respect to the analysis of the 1993 data. Substantial extension of the kinematic range towards low
Q
2 and
x has been achieved using dedicated data samples and events with initial state photon radiation. The structure function is found to increase significantly with decreasing x, even in the lowest accessible
Q
2 region. The data are well described by a Next to Leading Order QCD fit and the gluon density is extracted.

A measurement of the proton structure function F_{\!2}(x,Q^2) is reported for momentum transfer squared Q^2 between 4.5 GeV^2 and 1600 GeV^2 and for Bjorken x between 1.8\cdot10^{-4} and 0.13 using ...data collected by the HERA experiment H1 in 1993. It is observed that F_{\!2} increases significantly with decreasing x, confirming our previous measurement made with one tenth of the data available in this analysis. The Q^2 dependence is approximately logarithmic over the full kinematic range covered. The subsample of deep inelastic events with a large pseudo-rapidity gap in the hadronic energy flow close to the proton remnant is used to measure the "diffractive" contribution to F_{\!2}.
